Application of Edge Detection on Large Lump Detection
Detecting large lumps of oil sand is a critical step which protects exploitation facilities from jamming. This report presents a method that detects large lumps with edge detection and edge classification. The approach applies Gaussian based local scale control algorithm to detect edges in oil sands, then extracts intensity features as well as geometry features for edge classification. Trained ...
متن کاملNeural coding of passive lump detection in compliant artificial tissue.
Here, we investigate the neural mechanisms of detecting lumps embedded in artificial compliant tissues. We performed a combined psychophysical study of humans performing a passive lump detection task with a neurophysiological study in nonhuman primates (Macaca mulatta) where we recorded the responses of peripheral mechanoreceptive afferents to lumps embedded at various depths in intermediates (...
متن کاملHuman Hips, Breasts and Buttocks: Is Fat Deceptive?
‘hen males invest parentally, as in humans, males as well as W females are likely to exercise some choice (Darwin 187 1; Trivers 1972). The traits males use are expected to be those which reflect the female’s reproductive value (future lifetime expected reproduction; Fisher 1958; Williams 1966a,b) and current reproductive status (e.g., fertile, pregnant; cf. Gallup 1982, 1986). We will term thi...
متن کاملBreast-specific gamma imaging for the detection of breast cancer in dense versus nondense breasts.
OBJECTIVE The purpose of this study was to evaluate the sensitivity of breast-specific gamma imaging (BSGI) for the detection of breast cancer in dense versus nondense breasts. MATERIALS AND METHODS This was a retrospective study of 341 women with biopsy-proven breast cancer diagnosed from January 2004 to August 2009 who underwent BSGI before surgical excision. Patients with predominantly fat...
متن کاملOptimization of PCR-ELISA in Detection of Human Cytomegalovirus Infection
Abstract Background and Objective: Human Cytomegalovirus (CMV) is an important cause of congenital viral infection that can lead to serious diseases and complications in infants. Application of rapid, sensitive, and specific HCMV detection methods is necessary for congenital infection detection. We aimed to optimize the use of PCR and ELISA for detection of HCMV in infants. Material and Methods...
